A New Twist on $Z \to b {\bar b}$
Abstract
Description
A new mechanism is proposed to explain the "anomaly" in $Z \rightarrow b {\bar b}$ resulting in a prediction of a new, non-sequential fourth family whose masses could all be below $M_W$, thus opening up an exciting porpect for near-future discoveries at LEP2 and possibly at the Tevatron.
